plenum chamber

plenum chamber

[′plen·əm ‚chām·bər]
(engineering)
An enclosed space in which a plenum condition exists; air is forced into it for slow distribution through ducts.

Plenum chamber

An air compartment maintained at a pressure slightly above atmospheric, to deliver and distribute the air to one or more ducts or outlets.

plenum chamber

In an air-conditioning system, an enclosed volume which (in a supply system) is at a slightly higher pressure than the atmosphere and is connected to a number of branch supply ducts, or which (in a return system) is at a slightly lower pressure than the atmosphere and is connected to a number of return grilles; a plenum, 1.

A component of a jet engine designed to hold air at a pressure slightly higher than that of the surrounding air. Plenum chambers stabilize the pressure of the air before it enters the compressor.
